Authorization

Authorization is the process of granting or denying access to digital resources based on predefined permissions. In healthcare and other secure systems, authorization ensures that only approved users can perform specific actions or access sensitive information. It plays a vital role in protecting data, systems, and patient confidentiality.

Authorization vs Authentication

Authentication verifies a user’s identity, while authorization determines what that verified user is allowed to do. These two steps work together to control access. For example, after logging in, a doctor may view medical records, but a receptionist may only schedule appointments.

This distinction is essential – Authentication answers “who are you?”, and authorization answers “what can you do?”

Common Authorization Models

Several Access Control models help manage authorization:

• Role-Based Access Control (RBAC) – Grants access based on user roles, such as nurse, administrator, or IT staff.
• Attribute-Based Access Control (ABAC) – Takes into account attributes like department, device type, or time of day.
• Discretionary Access Control (DAC) – Allows users to manage access to their own resources.

Each model serves different security needs, and organizations often combine them for better flexibility and control.

Where Authorization Happens

Authorization can be enforced at multiple levels:

• Network level – Manages access to internal systems or cloud infrastructure
• Application level – Controls what features or functions users can access
• Database level – Restricts access to specific records or tables

These layers work together to ensure secure, role-based access throughout the system.

Managing Authorization Policies

Administrators define access rules through policies that outline who can access what, when, and under what conditions. These rules may be implemented using Access Control Lists (ACLs), permissions, or policy engines.

At Healthcare Integrations, we help organizations implement secure authorization frameworks. Our healthcare Interoperability consulting and API integration services ensure access policies align with both Clinical Workflows and compliance standards.

Authorization is essential for maintaining system integrity, confidentiality, and availability. When implemented properly, it helps organizations prevent breaches, reduce internal risks, and maintain regulatory compliance.
